Programmable Registers
Address:
31.7.26 Programmable Burst Size Register (HW_USBCTRL_BURSTSIZE)
This register is used to control dynamically change the burst size used during data movement
on the initiator (master) interface. This is a read/write register. Writes must be DWORD
writes. The default value is 0x00001010.

Internal TT Hub Address Representation.
Default is 0 (Read/Write). This field is used to match against the Hub Address field in QH and siTD to
determine if the packet is routed to the internal TT for directly attached FS/LS devices. If the Hub Address
in the QH or siTD does not match this address then the packet will be broadcast on the High Speed ports
destined for a downstream High Speed hub with the address in the QH/siTD.
